A new paper got released by Meta and for me it is an interesting research direction. Paper name: Self-Rewarding Language Models 1. Main Vision of the Paper: A new concept where language models generate and evaluate their own training data, leading to continuous self-improvement in performance. 2. What is the current problem: Conventional language model alignment often relies on fixed reward models based on human preferences, limiting the model's potential to human performance levels. Both RLHF and DPO is bottlenecked by the size and quality of the human preference data. 3. Addressing the Problem: The paper addresses this limitation by proposing an innovative training approach where the language model acts as its own judge, generating and evaluating new training data iteratively. This self-rewarding mechanism enables the model to continually refine its performance and reward modeling ability, transcending the constraints of human-based training data and fostering a cycle of ongoing enhancement. Algorithm overview: Starting Point: 1. Begin with the Llama 70B model, already fine-tuned on OpenAssistant data, which provides a strong foundation in understanding and generating human-like responses. 2. Generation and Evaluation: The model generates a variety of responses to a single prompt, such as "Suggest ways to reduce carbon footprint in daily life." Multiple creative and practical ideas are produced by the model. 3. Self-Judging: Using the same model, each response is evaluated and ranked based on criteria like feasibility, environmental impact, and originality. 4. Training with DPO: Direct Preference Optimization (DPO) is applied, using the rankings from step 3 to re-train the model, enhancing its response quality and judgment accuracy. 5. Iterative Process: Steps 2 to 4 are repeated for three iterations, leading to progressive refinement in the model's ability to generate and evaluate responses, thus improving both its creative generation and evaluative skills. This approach is a very innovative way to solve the dependency on human feedback and I think the future is a hybrid approach of using both human-preference and LLM as a judge model. I have a few concerns on the approach especially how it can be used for addressing magnifying bias while training. At HTCD, we have developed a similar algorithm that uses a combination of Large Language Models (LLMs) to create a self-rewarding loop. This loop enhances the accuracy of a smaller LLM in a specific domain. [More details very soon] Link to the paper is in comments. #knowledgesharing #generatieveai

🚀 Excited to present our work “Large Language Models Can Self-Improve At Web Agent Tasks”! We show that synthetic data self-improvement boosts task completion by 31% on WebArena and introduce quality metrics for measuring autonomous agent workflows. Training LLMs to act as effective web agents has been challenging due to a lack of training data. Our research demonstrates that LLMs can navigate and perform actions in complex environments guided by natural language instructions. We explored self-improvement techniques where LLMs fine-tune on data they generate themselves, assessing their improvement over the base model on the WebArena benchmark. This includes tasks like posting on subreddits, navigating GitLab, and shopping sites. We tested three synthetic training data mixtures (in-domain, out-of-domain, and mixed data) and found that all improved performance. The best results came from a mixture of in-domain and out-of-domain examples, significantly boosting capabilities and quality. To measure improvement, we developed new metrics assessing performance and capabilities. We extended the VERTEX score via Dynamic Time Warping for variable trajectory comparisons, providing deeper insights beyond aggregate-level completion scores. Our findings suggest that LLMs can acquire new capabilities, with net gains observed in all self-improved models. The self-improved agents also showed increased robustness, especially in functional correctness, ensuring stable performance. We provide new insights into unsupervised self-improvement techniques on complex, multi-step agent environments, such as web environments for LLM-based agent workflows. Overall, we demonstrate how our approach can help improve autonomous (web) agents. 🙏 A huge thank you to our amazing team and to the outstanding collaboration between the University of Pennsylvania, Johannes Kepler Universität Linz and ExtensityAI: Ajay Patel, Markus Hofmarcher, Claudiu Leoveanu-Condrei, Chris Callison-Burch, Sepp Hochreiter 📄 Read more in our paper on arXiv: https://lnkd.in/dPuzTWB6 💻 Check out our code on GitHub: https://lnkd.in/d5VAf-kj #AI #MachineLearning #LLMs #Agents

#copied Here's what to know about 𝗢𝗽𝗲𝗻𝗔𝗜'𝘀 𝗹𝗮𝘁𝗲𝘀𝘁 𝗺𝗼𝗱𝗲𝗹, 𝗚𝗣𝗧-𝟰𝗼, illustrated👇👇👇 The latest model GPT-4o ("o" stands for omni) excels in an array of tasks compared to its previous counterpart, GPT-4 Turbo. Here are key specs: 𝟭. 𝗠𝘂𝗹𝘁𝗶-𝗺𝗼𝗱𝗮𝗹𝗶𝘁𝘆 Unlike GPT-4T which required separate models per data type, GPT-4o processes text, voice and vision in a single model. This greatly improves comprehension and reduces latency from text-to-voice, voice-to-voice and etc. 𝟮. 𝗖𝗼𝘀𝘁-𝗘𝗳𝗳𝗲𝗰𝘁𝗶𝘃𝗲 GPT-4o is 50% cheaper than GPT-4 turbo. For instance, the cost of 1M token (equivalent to about ~700K words) for GPT-4 Turbo is $10 for input and $30 for output. GPT-4o is fraction of that cost, $5 for input and $15 for output. From a developer's perspective, I'm loving this! 𝟯. 𝟱𝟬+ 𝗟𝗮𝗻𝗴𝘂𝗮𝗴𝗲𝘀 GPT-4o is much more flexible in multi-lingual capability as it now supports more than 50+ languages. Plus, it has shown to be better in non-English tasks. 𝟰. 𝗜𝗻𝗰𝗿𝗲𝗮𝘀𝗲𝗱 𝘀𝗽𝗲𝗲𝗱 There's reduce latency in generating tokens. It's 2x faster in speed. I had a chance to test this in Open AI's playground, and, in deed, I do see a sharp contrast in the text generation speed for GPT-4o vs GPT-4 turbo for the same prompt. 𝟱. 𝗛𝗶𝗴𝗵𝗲𝗿 𝗿𝗮𝘁𝗲 𝗹𝗶𝗺𝗶𝘁 There's increased rate limit for requests-per-minute (RPM) and tokens-per-minute (TPM). This will be useful especially for high chatbots with high QPS. 𝟲. 𝗣𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲 Across text tasks, GPT-4o has shown to achieve 88.7% MMLU (vs 86.5% for GPT-4T and 83.7% for Gemini Ultra), 76.6% MATH (vs 72.6% GPT-4T and 53.2% for Gemini Ultra). Also, it has shown improved evaluations in audio ASR, translation, zero-shot and vision understanding. 𝟳. 𝗦𝗮𝗳𝗲𝘁𝘆 They used 70+ domain experts across social psychology, fairness and bias, and misinformation to identify and mitigate risks. *I'd have to say that from a consultant's standpoint, I'm looking forward to getting my hands on with the latest model's API and see its fortes and weaknesses in prompt response for RAG-based, data analysis tasks. 2X gain in latency with 50% cheaper in token input/output is quite huge from business perspective as well.
